Troubadour

A Sunset Strip music scene staple since 1957, this low-key venue hits all the right notes with diehard concertgoers. Elton John performed on the Troubadour stage early in his career, so go for the hottest contemporary acts or channel your inner record executive and try to spot the next big thing.

Lena Dunham has already proven her skill as a writer, director and actress, and now the Girls star has demonstrated one additional talent: supportive rock star girlfriend to Jack Antonoff.

The HBO darling, 27, was spotted with a small group of friends in the VIP section of the Troubadour in West Hollywood Wednesday night "laughing, clapping and pointing out her man's antics," a source tells PEOPLE.

"She stood almost the entire time," the source continued. "She bopped her head and occasionally pointed to the stage and whispered in her friends' ears with a big smile on her face as though she was so proud of her man. It was clear she was focused on him the entire night."

No hard feelings, apparently, for Kim Kardashian toward singer Prince after he ushered her off the stage recently at New York's Madison Square Garden due to her lack of dancing skills. On Wednesday night, Kardashian turned up in the VIP balcony at Prince's surprise last-minute show at the intimate Troubadour club in West Hollywood. She still didn't dance, but she did sway a bit to the music in between sending texts and a Twitpic of Prince with the caption, "Nothing compares."

The new mom arrived with her parents – Joe and Tina Simpson – to see the group preview songs off their upcoming album, Folie à Deux. But she didn't pull an all-nighter. "They're new parents," the source says. "They didn't want to be away from the baby too long."

Zach Braff and Scrubs castmate Sarah Chalke, checking out upcoming singer-songwriter Ingrid Michaelson at the
Troubadour in West Hollywood. According to a fellow concertgoer, Braff was
wearing a grey hoodie, attempting to go incognito at the gig, while Chalke,
in a navy blue coat, was more "in the open." The pair stood at the bar
before moving to the other side of the club.
